REFLECTOR: FOR WATER5GAGES.

SPECIFICATION forming part of Letters Patent No. 389,802, datedSeptember 18,1888.

Application filed Juno 5, 1888.

To aZZ whom it may concern:

Be it known that I, SOLOMON PORTER GIL- BERT, a citizen of the UnitedStates, residing at St. Clair, in the county of St. Clair and State ofMichigan, have invented a new and useful Improvement in Reflectors forWater- Gages, of which the following is a specification.

My invention relates to an improvement in reflectors for water-gages forsteam-boilers, whereby rays of light may be concentrated on thewater-gage to render the column of Water therein more clearly visible;and it consists in the peculiar construction and combination of devicesthat will be more fully set forth hereinafter, and more particularlypointed out in the claims.

In the accompanying drawings-Figure l is a perspective view of areflector embodying my improvements, showing the same arranged on awater-gage. Fig. 2 is a detail perspective view of the reflector,showing the same detached from a water-gage, a portion of the case ofthe reflector being removed to illustrate the construction thereof.

A represents a looking-glass of suitable size, the back of which isformed by metallic plate B. which has its side and upper and lower edgesbent around the edges of the mirror, as shown. In the lower corners andin the lower edge of the case, at suitable distances between the lowercorners thereof, are made openings C. This arrangement and constructionof the case enables water, which may be deposited on the reflector asthe result of condensation, to pass from the lower side of the case, andprevents the same from lodging be tween the back of the glass and thecase and injuring the coating of mercury on the glass.

D represents the holder, the construction of which is as follows: Apiece of wire of suitable length and diameter is bent back and forth atits center to form loops E, whereby the holder may be contracted orexpanded in a longitudinal direction. Circular open hooks F are thenformed in the wire at suitable distances from the loops E, and areadapted to engage the upper and lower edges of the case of thereflector, the back of the same bearing against the loops E. The ends ofthe wire are Serial No. 276,068. (No model.)

so as to concentrate the rays of light on the gage-tube and enable theheight of the column of water therein to be more readily distinguished.

Having thus described my invention, I claim-- 1. The reflectorcomprising the mirror, having its back formed of sheet metal, the edgesof the metal back being bent around the edges of the reflector, and saidmetal back being provided with the opening C in its lower side,substantially as described.

2. The combination of the water-gage,and the holder having the hooks Fand the clamps G, the latter being pivotally attached to the gage, sothat the holder may be swung around the same and the reflector engagedby the hooks F, and thereby secured to the holder, substantially asdescribed.

3. The combination ofthewater-gage,and the holder having the hooks F andthe clamps G, the latter being pivotally attached to the gage, so thatthe holder may be swung around the same, substantially as described.

4. The holder having the loops E, and pro vided with the hooks F, forthe purpose set forth, the holder being further provided with the armshaving the semicircular springclamps G, substantially as described.

5. As a new article of manufacture, the refiector-holder forwater-gages, comprising the wire having the loops E, the hooks F, to engage the sides of the reflector, and the arms provided with thespring-clamps G, for the purpose set forth, substantially as described.

In testimony thatI claim the foregoing as my own I have hereto affixedmy signature in presence of two witnesses.

SOLOMON PORTER GILBERT.
